8FS: Full Suspension 8sp Folding Bike

Our affordable full suspension folding bike

The Downtube Model 8FS is simply the best low budget full-suspension folding bike on the market. Thanks to its top-of-the-line front and rear suspension system, the 8FS is also one of the comfiest foldable bikes you'll ever ride. With the portability of a foldable bike and the comfort of a full-sized bike, the 8FS combines the best of both worlds.

Having the same frame and fork as the premium 9FS, the 8FS is a rock-solid bike when it comes to quality. To make it a budget bike, we fitted the 8FS with less expensive parts than the 9FS. This careful value-engineering produces a full-suspension 8sp bike that costs under $350. That’s value you won't find anywhere. Not even close!

In addition to its super comfortable suspension system, the 8FS has plenty of built-in quality that makes driving this bike around a most pleasing experience. Its high-end Microshift drive train and its top-notch frame work with the suspension system to provide a flawless riding experience that will make those long trips seem much shorter.

The 8FS comes fitted with a front dérailleur braze on (with cable routing), head tube bag interface, pump interface, kickstand mount, two water bottle braze ons, rack braze ons, and a removable frame protector that can act as a kickstand when folded.

When folded, the small frame of the 8FS is easy to fit inside any vehicle. It’s even easy to carry over your shoulder or on your back like a backpack.

In addition to the existing features of the 8FS, we offer free standard upgrades which include the head tube bag interface, pump interface, and water bottle braze on (the pump and cage are not included).

This bike isn't just a bargain; it’s the best deal on a similar bike that you'll ever find. Our low-cost, high-value business model helps you get the best quality for the best price. At under $400, the 8FS is an incredible value.

If you are looking for a full suspension bike, the 8FS is definitely the bike for you.

Our 4th Downtube FS folding bike. Very well made and problem free.

I own an 8FS (my last one was a 9FS). My wife owns a 9FS. Both bikes are perfect for riding. We take them on vacation to the shore twice a year. We have had zero issues with the four that we have owned. Highly recommend!

Tremendous Value

I have a Dahon Jetstream full suspension bike. It was expensive, is relatively light, and has top-level components. The Downtube was purchased for my daughter. We went out for a ride together, and switched bikes back and forth for comparison. The Downtube is heavier and seems to have a longer wheelbase, but for recreational riding, which is why we bought it, it does an admirable job. It is well-made, and is a tremendous value for the money.

Purchased a second one!

I bought one for myself just over a year ago and my wife wanted one. She was impressed with its versatility for traveling. Nothing else comes close at the price point and it is fun to ride.

Love it!

Going to buy one for my wife too. Folds easily. Solid as a rock. Packs up in a bag. Stores easily in my RV.

8FS

Excellent bicycle for the money, came well packed and didn’t need much adjustment. Most importantly for a mail-order item, customer service from Yan could not be better. He knows and stands by his product, and is patient and knowledgeable with questions.

Wonderful bicycle - Better than expected

Great bicycle. The suspension functions quite well, brakes function well. The gearing is just right. Build quality is excellent. Easy to fold and lift. Highly recommended. Am looking for a rear rack - any suggestions?

Smooth on bumpy surfaces

Just have bought 8FS. It is my second bike from Downtube. Riding on bumpy surface I can feel a difference. It's worth it for me to have a full suspension bike. Although for my girlfriend Nova is better because of a lighter weight to carry.
